Re:Security Fixes (Score 2, Informative)

Security fixes for FreeBSD are released as part of the RELENG branch for a particular release version. 4.9 (presumably) includes all the security fixes which were released since the 4.8 release, which were announced on the 4.8 errata page. The 4.9 errata page is here. The security fixes are usually released concurrent with any vulnerability announcement, but it's still up to users to read the handbook and patch their own systems.
